What’s code push?

  • Over-the-air, instant updates for Flutter code on user devices.
  • Real problem for businesses.
    • Downtime = lost revenue.
    • Code push = insurance you can fix things quickly if they go wrong.
  • Every large app uses code push
    • Large install base = long store update time
  • A missing piece for adopting Flutter
    • Make your mobile team as productive as your web team.

We did the hard work, so you don’t have to

  • Custom Flutter Engine including Shorebird Updater.
  • Custom Dart compiler and interpreter.
    • Result: Update any Dart code (don’t have to predict where bugs might occur).
  • Differential patches (patch sizes are bytes, not megabytes)
  • Secure by design (SSL, Google Cloud, signed/verified updates)
  • Private by design (never see your code, don’t collect any user data)

Safe, you can ship today

  • Patches verified on-device.
  • Automated rollback on failures.
  • Your compiled binary is hosted on our servers. We never see your source.
  • Tracks latest Flutter Stable (within hours of release).

​

Designed to never be worse than your current setup.

Safe for Stores

Play Store

“An app … may not modify, replace, or update itself using any method other than Google Play's update mechanism.” … “This restriction does not apply to code that runs in a virtual machine or an interpreter”

​

Shorebird uses the Dart Virtual Machine. Similar to how other apps use JavaScript or Lua.

App Store

3.2.2. “Application may not download or install executable code. Interpreted code may be downloaded…”

​

​

Shorebird uses a custom Dart interpreter on iOS to both comply with store guidelines and provide excellent performance.
